8.2V 1Watt Zener Diode 1n4738

The 1N4738A is an 8.2V, 1W silicon planar Zener diode manufactured by onsemi, engineered for precise voltage stabilization and clipping circuits. Housed in a hermetically sealed, axial-leaded DO-41 glass package, this durable component features a standard 5% voltage tolerance and an oxide-passivated junction for excellent operating stability. It operates at a nominal Zener voltage of 8.2V under a 31 mA test current while maintaining a low maximum dynamic impedance of 4.5 Built to withstand demanding environments, it supports an operating temperature range from -65°C to +200°C, making it a reliable reference element for mid-power industrial and commercial electronics.
